  • peculiarity/
  • function/
  • parameter
  • ■  MU calibrating mode: It can calibrate merging unit (MU) based on current input type and FT3 data input type.

    ■  ECT/EVT calibrating mode: It can calibrate electronic current/voltage transformerECT/EVTbased on IEC61850-9-1,9-2, 9-2LE, IEC60044-7/8 FT3,FT3LE data format.

    ■  6-phase synchronous sampling and simultaneous checkout: It can simultaneously check out 6-phase voltage&current channel. Synchronous sampling of 6 channels ensure the definitely synchronous waveform of every phases and visual data display, including displaying standard, calibrated waveform, differential,angle difference and composite error, discrete type message waveform, harmonic waveform and MU full access waveform. This can chronically observe ECT/EVT or MU linearity and stability.

    ■  Multiple optical port input: The dual-channel IEC61850&IEC60044 data interface and two synchronous clock input&output interface can simultaneously receipt two MU or EIT output to get nuclear phase calculation about relative channel.

    ■   Automatic configuration: Supporting the SCD file import, it can automatically identify MU channel information and configurate relative standard access to channels.

    ■  Multiple timing pattern: Synchronous clock includes IEEE1588, IRIG-B code and second impulse PPS etc. Flexible configuration.

    ■  Operating&controlling by laptop: To test with circumscribed laptop. Powerful functions, convenient operation. Automatic storage of testing results.
